Description

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A DEVICE FOR PROVIDING TENSION AND PROPERTY OF ANTIGRANIZATION, ANTI-INSECTS, OR CLIMATE NETWORKS.

Object of the invention. The object of the invention is a device for providing tension and immobilization of anti-hail, anti-insect or climatic networks, which are installed through rows of support posts containing longitudinal cables fixed above their respective rows of posts.

These nets are attached by the side or by their central part to these longitudinal cables and are connected to each other in a discontinuous manner by their other lateral end; forming in said networks a two-water cover, with the ridge on the longitudinal cables and the bottom just in the center between these rows. The network can be whole from center to center of contiguous roujas or can be two medium networks united in the ridge.

The structures, in order to avoid lateral movement, usually hold transverse wiring which joins the posts perpendicular to the longitudinal cables.

This tensioning device has particular constructive features oriented to achieve a stable fixation of the nets by the zone corresponding to its lower end, that is, by the intermediate zone of two rows of posts, longitudinally along the whole net and supporting from the transverse wiring structure.

In this central zone, the nets are not currently fixed effectively and their movement by wind and excessive hail loads can lead to premature breakage of nets.

Field of application of the invention.

This device for tensioning and immobilization of nets is applied in the agricultural sector; although the protection of public or private outdoor areas intended for the parking of vehicles or the installation of various equipment is not excluded.

State of the art.

Currently there are different protection devices with nets on the market, and those which protect a greater range comprise: rows of support posts on which are mounted first longitudinal cables, where it is fixed, by means of clips or similar elements , the upper end of the protective nets, said nets being fixed to each other, in a discontinuous fashion, at their lower end; so that the pairs of nets arranged between the two rows of consecutive posts form a kind of two-water cover, descending to the longitudinal middle zone of the space delimited by the rows of consecutive poles mentioned.

Because these protective devices are installed outdoors, the attachment between the second ends of the nets, which converge in the lower zone, must be fixed to each other in a discontinuous manner so that the hail falling on the nets can descending by gravity into the central zone and falling by its own weight through the open spaces defined between the successive fixations of the lower end of the nets.

Another requirement of such anti-hail protection devices is that the nets form said downstream deck to two waters and that they remain in said position with a certain tension, in order to prevent the wind from being able to rise and cause an uncontrolled movement of the nets submitting - to accelerate deterioration and to ensure that hailstones that fall on the nets are discharged to the central area of evacuation and do not form pockets in intermediate zones, carrying the nets with a weight that can cause their breakage by the zones of engagement with the first cables and by the lower zones of fixing the nets together.

The means currently employed for obtaining such tensioning and fixing of the nets by the lower zone thereof consists in the use of elastic bands located below or above the nets and that the nipples of the lower ends of nets are engaged at one of their ends, and by the end opposite the poles, the trellis wires of the respective consecutive rows or, also, there are also elastic systems that connect an intermediate reinforcement of the net between them forging the flat network and a small network funnel in the center between rows.

One drawback of such elastic bands is that, when exposed to the elements and weather, they deteriorate rapidly, and they need to be replaced at a high frequency, which leads to a significant economic and ecological cost.

These elastic bands represent other drawbacks, among which are worth mentioning, that engage directly into the net and work in a punctual way, which can cause its breakage, as well as the hindrance to the passage of working machines for pruning or harvesting, which suppose those which are arranged below the net and are inclined downwards to the point of attachment to the corresponding post. The inventor of the present invention is not aware of the existence of other antecedents of protection devices with nets, similar to those of the type described and that allow satisfactory resolution of the exposed problem.

Disclosure of the Invention. The device for tensioning and immobilizing anti-whipping, anti-insect or climatic networks, which is the object of the present invention, has particular constructive features oriented to satisfactorily solve the problem previously discussed, having means for fixing to the lower end of the nets, from the the upper part thereof without using resilient means and so that said fastening means does not constitute an obstacle for working machines (pruning, harvesting, etc.).

This tensioning and immobilizing device is applied to nets fixed at an upper end to longitudinal cables mounted on rows of poles connected top by cross-cables; said nets being discontinuously joined together at their lower end to form a two-water cover with the ridge on the longitudinal cables and the lower end centered longitudinally between two rows of posts.

According to the invention, said locking device comprises V-shaped positioners having a web out of which two wings are oriented towards the upper zone and are fixed to the transverse cables of the frame, with the possibility of lateral adjustment and at that time, by means of fixing clamps; also comprises a synthetic or metallic longitudinal wire or cable which attaches to the web of all V-shaped positioners on its lower part and which is placed in close contact with and above the junctions of the protection nets in the center of the rows, , in the lower part of the chapel, where the hail will be discharged. This device is in contact with the network joints, but allows the network to disengage freely in the event of an out-of-normal hail drop.

In one embodiment of the invention, said device optionally includes wires, cables, or elastics placed under the net to support it when opening or closing, and thus to avoid tearing until it touches the growing area or underneath elements and avoid wind breakage.

These wires, cables or elastics go from one ridge to the other, descending parallel to the net to its lower part and continuing to the next ridge of the consecutive row.

They rest on the lower part of the "V" positioner's web, without coming to join it. It is of interest that such cables, wires or elastics are flexible and allow their length to be increased so that the net can descend in the event of a large drop of hail.

With the features mentioned above, the longitudinal or metallic or synthetic wire or cable located on the network joints in the central part of the protected rows prevents the zone of attachment of the lower ends of the protection nets from being able to move uncontrolled laterally and vertically by wind effect, for example. Furthermore, mounting the positioners on the transverse cables by means of fixing clamps allows to vary both laterally and in height the position of the webs of said positioners and to make an adjustment of the inclination of the two waters formed by the nets.

On the other hand, the choice of elastic lower cables or yarns supporting the nets together with the second longitudinal rope provides a more stable attachment of the nets in a position of use, in addition to preventing their fall on the lower crops during the folding and annual folding of the nets on the ridges.

Figure 2 shows a view analogous to Figure 1 without protection networks. Figure 3 shows a partial front view of Figure 1 in which the different network securing elements can be observed. Figure 4 shows a view analogous to Figure 1 with the nets collected for the respective support rows resting on the elastic bottom support ropes. Figure 5 shows a detail of one of the positioners, mounted through fixing clamps to a transverse cable. Figure 6 shows, schematically, an exploded view of one of the securing plates of the lower ends of the nets.

Preferred mode of the invention.

As can be seen in Figure 1, the device of the invention is applied to the tensioner of nets mounted on a support structure comprising rows of support posts (la, Ib), being fixed on the upper ends of the posts (la , Ib) of each row first longitudinal cables (11a, 11b); and on the upper ends of the poles (la, Ib) of different rows a transverse cables (3).

The tensioning nets (2a, 2b) are fixed in a known manner by an upper end (21a, 21b) to the respective first longitudinal cables (11a, 11b) and fixed to each other in a discontinuous fashion by their lower end (22a , 22b), said nets (2a, 2b) forming a two-water cover, descending to said lower ends (22a, 22b). The lower ends (22a, 22b) of the nets (22a, 22b) are realized by means of pressure-detachable plates (8), defining the lower ends (22a, 22b) of the nets (2a, 2b) between the zones (8) holes for the gravity fall of the hail accumulated on said protection nets. The net tensioning device according to the invention comprises V-shaped rod positioners (4), which have a web (41) out of which two wings (42) are directed towards the upper zone and fixed to said ones (3), with lateral adjustment and height adjustment, by means of fastening clamps (5) known per se and used for securing the cables or rods with different angles. The device comprises a second longitudinal wire (6) of metallic or synthetic material which is fixed to the web (41) of said positioners (4) and disposed above the lower ends (22a, 22b) of the nets and plates ( 8) for securing said lower ends of the nets (2a, 2b).

This second cable or longitudinal wire 6 prevents the lower ends of the nets 2a, 2b, fixed between the plates 8 from being able to rise by the wind action or that the hail can be accumulated in the form of pockets, minimizing the deterioration of networks; in addition, the height of this second longitudinal cable 6 can be adjusted by adjusting the height of the positioners 4 in relation to the transverse cables 3, ensuring a correct tensioning of the nets 2a, 2b, inclined in the transverse direction.

In the example shown in Figures 1 to 4, this device comprises elastic bottom support cables 7, provided with two upward branches from the web 41 of the positioners 4 to the upper end of the posts 1a, 1b ) of consecutive ranks.

As shown in Figure 3, said resilient lower cables 7 also allow support of the nets 2a, 2b in an open position, i.e., collected towards respective rows of posts (la, Ib) when the lower ends ( 22a, 22b) of the nets are not fixed to each other in a discontinuous or intermittent manner by the plates (8).

Finally it is worth mentioning that the fixing of the longitudinal cables (11a, 11b), the transverse cables (3) and the elastic lower cables (7) on the upper ends of the posts (1a, Ib) can be carried out by means of analogous clamps used to secure the positioners (4) to the transverse cables, but in this case screwed onto the upper end of said posts (1a, Ib).

Once the nature of the invention has been sufficiently described, as well as an example of preferred modality, it is clear to the proper effect that the materials, shape, size and arrangement of the elements described may be modified, as long as it does not imply a change in the characteristics essential components of the invention claimed in the sequence of the present disclosure.
